It's been a busy test week for BMW at the Nurburgring, which includes some more testing on the F32 435i M Sport. Not much is revealed in these photos, but they provide more looks at how the 4 Series (F32) looks in motion.

This is a 435i M Sport in Estoril Blue II. The M Sport bumpers remain under camouflage. The headlights feature the optional full LED headlights with squared-off corona rings.

The M Sport brakes are fitted, but the M Sport wheels are not. See the wheels 4 Series lineup (from the 4 Series order guide) posted below for what the M Sport wheels will look like (as well as on the blue 4 Series spotted at the airport reposted below).
